Improvement in bobbins for spinning-machines



CHARLES THOMAS SMITH, 0F U'IICA, NEW YORK.

IMPROVEMENT IN BOBBlNS FOR SPINNING-MACHINES.

Specification forming part of Letters Patent No. 58,903, dated October 16, 1865.

To all whom 'it may concern:

Be it known thatI, CHAnLEsTnoMAs SMITH, of Utica, in the county of Oneida and State of New York, have invented a new and useful Improvement in `Wood Bobbins, new in use in Wooleirmills; and I do hereby declare that the following is a full, clear, and exact description of said invention, reference bein g had to the annexed drawings, with letters ot' reference marked thereon, being a part of this specitication.

The nature oflny invention or improvement in bobbins consists in making the bands or tubes of sheet-zine.

The bobbins, after they are wound, have to go through a steaming' process, which has the e'ect to prevent the yarn from kinking at each side of the piece of cloth while the weaving is r going on. During this process these zinc tubes or barrels are found to be superior to all others, as they do not rust or corrode, as would be the case if made ot' sheet-iron; and they will not shrink or swell or grow rough, as is the case in wooden bobbins, which swell in the steaming process, and sometimes before used they shrink to such a degree that whole cops often slip oli' while weaving, causing great Waste and loss. The bobbins made of zinc are consequently smooth, and the yarn all runs ott' Without waste or loss.

Another advantage these possess over wooden bobbins is this: They are smaller and stronger and grow smooth by use; and as all bobbins for Weaving have to be wound the same size, they are found to hold one-third more yarn and they are as lasting as the machinery itselt',and not liable to get out of order.

To enable others skilled in the art to make and use my invention, I will describe their construction and operation.

First. 'Ihe barrels or tubes are madcoi sheetzine. The ends ofthe tubes A,1, and C, or l, 2, and 3, are tilled with t'nsed metal atl), Section No. 3, to make them strong, with a taper hole in the end to admit of a taper spindle, as seen in Section No. 3 at I).

Second. Section No. 3, at E, shows the manner of securing the tubes or barrels to the Wooden ilanges F, which is done by pins or by indentations in the metal on the inside oi' the tube into the wooden end or iianges, or by dividing or splitting the end ot' the tube into four sections, and turning them over the end onto the tlanges, which fasten them securely.

Vthat I claim as my invention, and wish to secure by Letters Patent, is-

A tillingbobbin the tube or barrel ot' which is formed or manufactured ot` sheet-zine, with a wooden head or flange, as above described, the bore ot' the barrel at its tip bein g made tapering, in the manner and t'or the purpose as herein set forth.
